Application filed October 7,1902. Serial No. 126,278.

. Utica, in. the county of Oneida and State of New York, have inventedcertain new and useful Improvements in Magazine-Firearms, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The invention relates to an improvement in magazine-firearms, consistingparticularly in a construction whereby one of a plurality of containedcartridges is automatically moved into a firing position by the actionof the mechanism.

The invention further comprises a new and improved mechanism for therapid breeching and unbreeching of the gun.

n connection with my improved magazine-firearm I prefer to use a type ofcartridge known as rimless, such as shown at 1, wherein the contour ofthe body of the shell has no projecting rim at the base.

breeching-lever.

The barrel 2 of the gun is threaded at its inner or rear end and isscrewed into the gun-frame at 3. In rear of the connection between thegun-frame and barrel I arrange the magazine, comprising a shell-likestructure, preferably formed in two sections 4 and 45*, the former ofwhich is rabbeted at 1.2 and 13 on its lower edge to receive the upperedges of the lower section 4*. Section 4 of the magazine is cut away onthe right-hand side, as at 5, Fig. 5, to permit the ejectment of thecartridge, and in the opposite wall of this section of themagazine-frame I form a longitudinally-arranged groove 6, in which issupported the ejector 7,compri sing a springhook secured by a screw 8,as clearly-shown in Fig. 12.

The breech-bolt 26 is adapted for longitudinal movement within themagazine of the gun, preferably riding on oppositely arrangedinwardly-projecting ledges 10 and 11, secured to or formed integral withthe walls of the upper section 4 of the magazine. At the forward end thebreech-bolt is provided with a pin or trunnion 31, arranged forlongitudinal travel in groove 32 in the wall of the magazine, wherebythe forward end of the breech-bolt is compelled to travel in a straightline. The rear of the breechbolt is provided with a breeching-shoulder33, arranged to engage a shoulder 33 in the frame of the magazine, or,more properly speaking, the forward edge of the upper frame-tang 34.

The breech-bolt is non-rotating and in the present instance preferablysquare in section, being provided near its lower edge on opposite sideswith shoulders 30, arranged to cooperate with the ways and 11 in theupper section of the magazine-frame. The front end of the breech-bolt iscut away to form an inverted-U-shaped recess 27, the edge flanges 28forming this recess being spaced sufficiently apart to admit the buttendof a cartridge within the recess. An extractor 29 is arranged to form aportion of the flange 28, being secured in the wall of the breech-boltwith its hooked end normally projecting within the recess 27. By thismeans the extractor 29 will engage the rim or depression in the base ofthe cartridge and ment.

hold the cartridge securely in front of the breech-bolt to permit thedischarge of the cartridge. Furthermore, in the opening of the action ofthe gun the extractor 29 operates to withdraw the cartridge from thebarrel and move the same rearward with the breech-bolt. A groove 9,formed in the wall of the breech-bolt, receives the headed end of theejector-hook 7, and in the unbreeching of the gun the hook 29 will movethe cartridge rearward with the breech-bolt until the head of thecartridge strikes the ejector-hook and arrests its rearward move- Theextractor 29, being still in en gagement with the cartridge, willoperate to throw the latter'from the gun through the opening 5 in themagazine.

The breech-bolt is partially hollow to receive the firing-pin, whichlatter is formed with a firing-point 37, arranged to be projectedthrough an opening 38 in the front wall of the breech-bolt. The"firing-pin carries a coiled spring 39, bearing at one end against thefront end of thefiring-pin and at the opposite end against a fixedabutment 41 in the breech-bolt. A pin 42, connected with the head of thefiring-pin, passes through the coiled spring and through the abutment41, being formed at its rear end beyond the breech-bolt with acocking-heel 43, the front face of which is formed with a curved recess44. A retractor is arranged to enter the recess 44 when the gun isfired, as illustrated in Fig. 9.

The magazine is provided with a carrierplate 14, formed on its uppersurface at one side of the longitudinal center with a rib or projection15. The walls 80 80 of the upper section of the magazine-frame adjacentthe ways 10 and 11. for the breech-bolt are curved inwardly to conformto the shape of the cartridges, and the rib 15 is located on thecarrier-plate 14 with particular relation to these curved surfaces, sothat the cartridge may be moved into proper position to be actuated bythe breech-bolt, as will be understood.

The magazine proper is of sufficient width to permit the cartridges tolie in staggered relation when viewed in section, so that they may bealternately engaged by the curved walls of the magazine to be projectedinto operative position. The rear edge of the rib 15 is cut away at 16to permit free movement of the breech-bolt in the event the carrierplateshould be projected into the path thereof. The lower face of thecarrier-plate is provided with inward projections 18 18 on oppositeedges to provide recesses, in which one end of the operating-spring 17is supported, the opposite end of which is detachably supported betweenlugs 19 and 19, formed in the shoe or detachable bottom for themagazine. This shoe is formed at its rear end with a hook 21 to engage arecess 22 in the rear wall of the magazine, while the forward end of theshoe is provided with an opening 23 to receive a screw 23 to secure theparts together. The screw 23 passes through sec tion 4 of the magazineand enters a threaded opening in section 4, while the rear portions ofthe section are held together by screw 24, the latter screw passingthrough the gun-stock.

To the rear of the breech-bolt I provide or form integrally a wing 46,formed with a slotted camway 47, which camway is vertical for a portionof its length and inclines from said vertical portion forward toward thelower end of the wing. For operating the breech-bolt I provide abreeching-lever 50, fulcrumed to the lower tang of section 4" of themagazine. This lever is preferably made in two parts a and a, securedtogether by rivets 52 52*, the construction being such as to provide afinger-recess, as shown. Section a is a curved arm arranged concentricto the pivot 51 of the lever and at its free end within the gun isprovided with a laterally-projecting stud 48, having a head 49, whichstud is arranged for travel in the camgroove 47 in the wing of thebreech-bolt, the head of the pin 49 serving to prevent separation of theparts in operation. Difficulty has been experienced in guns of thisgeneral type by reason of the concentric arm of the hand-lever 50springing laterally from operative connection with the wing of thebreechbolt and by reason of the parts wedging or twisting at theconnection between said wing and arm. I overcome these difficulties inthat the end of my concentric arm extends beside and parallel with aside face of the breech-bolt wing and is maintained in proper relationwith respect thereto by the lateral stud 48, extending through the slotand at its outer end having the enlarged fiat head 49 at the oppositeface of the breech-bolt wing and of greater diameter than the width ofthe slot. The free end of the section a of the lever 50 is arranged totravel upon and be supported by an antifriction-roller 55, journaledbetween ears 56 and 56 in the lower tang of the frame, whereby to braceand rigidly support the breeching-shoulder on the bolt in contact withthe breechingshoulders of the upper tang or section of the magazine. Arolling cam action is attained by the engagement of the inclined freeend of the con centric arm of the hand-lever with the roller 55, wherebygreat force and pressure are exerted with comparatively slight effort onthe breech-bolt in forcing the shoulders 33 33 nto tight engagement.

For withdrawing the firing-pin into inop erative position and holdingthe same in such position I provide retractor 45, hereinbefore referredto, which is pivoted on the wing of the breech-bolt at 58 and normallyheld in operative position by spring 59, arranged be tween its rearportion and the lower face of the breech-bolt when the gun is open. Whenthe action is closed, the retractor is in the po sition illustrated inFig. 9, being depressed by its forward edge engaging beneath a stud orantifriction-roller 59 which forces the rear end of the retractor intodepression 44 of the firing-pin heel. A depression 60 is formed on theforward edge of the wing of the breechbolt to engage saidantifriction-roller 59, which is mounted between lugs 62 62 the purposeof which depression. is to multiply the retracting energy in theoperation of the gun.

Advantages are attained by employing the retractor 45, having its frontend gradually reduced along the top edge to form a cam to cooperate withthe roller 59 with a powerful wedging lever action to withdraw thefiringpin. It will be noted that the retractor is not forked orbifurcated, but is reduced on a curved line from its upper edgeforwardly to its front end, thereby forming the single point or reducedend. Difficulty is experienced in the operation offorked retractors byreason of the weakening of the spring controlling the same which permitsthe forked end of the retractor dropping so low that the upper arm ofthe forked end engages the front projection, thereby causing jamming ofthe action and preventing operation of the retractor.

The sear 63 is pivotally supported on the stud carrying theantifriction-roller 59, the opposite end of which is provided with alaterally-projecting pin 63, arranged to engage a slotted opening 64 inthe upper end of the trigger 65. The trigger is pivotally supported at66 in the lower section of the frame and is spring-pressed by spring 68to prevent rattling of parts and yieldingly hold the sear and trigger intheir normal positions. The scar is provided with the usual engagingshoulder 82, and on one side and forward of such shoulder is providedwith a downwardly and forwardly inclined edge having a recess or stop70, forming the half-cock shoulder, as will be described. On the innerface of section a of the breeching-lever I provide an irregularcam-surface arranged to ride on the heel of the trigger to preventpremature discharge of the gun while the action is being closed. Whenthe action is in closed position and the trigger is pressed back torelease the firing-pin, the heel 68 of the trigger moves into notch 69of the section 0/ of the lever 50.

For holding the gun at half-cock the shoulder 70 engages the extremelower end of the firing-pin 43.

For locking the action when the gun is loaded and ready for use Iprovide a lockingpin 71, pivotally mounted in the stock and provided atits inner end with a cam or projection 73, arranged to be swung intocontact with the heel of the trigger, as clearly shown in Fig. 4. Thelocking-pin 71 is provided with an operating-finger 72 outside the gunand is held within a slotted tapering nut 75, having threaded engagementwith one wall of the stock, whereby any tension desired on the rod maybe secured by turning nut 75 to the right or left.

Assuming the action open and the magazine empty, when the parts will bein the position illustrated in Fig. 16 it will be understood that thecartridges are fed in the magazine through the opening 5 in position tobe successively engaged by the breech-bolt, it

being understood that the carrier-plate acts to successively projecteach cartridge into the path of the breech-bolt. As the breechboltadvances in closing the action the front recess receives the head of thecartridge, the extractor 29 engaging the groove in said head. In closingthe action the heel of the firing-pin is carried into engagement withthe shoulder 82 of the sear by an upward movement of thebreeching-lever, which contact arrests the forward motion of thefiring-pin, and as the breech-bolt continues to advance toward theclosing position the spring 39 is compressed ready to project thefiring-pin into contact with the cartridge by depression of the trigger,which disengages the shoulder 82 from the heel of the firing-pin. If itis desired to close the action and leave the gun half-cocked, it is onlynecessary to partially close the action until the firing-pin contactswith the shoulder 82 on the sear, when the trigger is operated todepress the sear and permit the end of the firing-pin to pass theshoulder 82 and engage the notch 7 0. If desired to wholly uncock thegun, the sear in the operation just described may be depressed to permitthe firing-pin to wholly pass it, as will be understood. It is obviousthat the action can be closed without cocking the gun by holding thesear depressed by the trigger, as the hand or finger lever is swung upto completely breech the bolt. To close the action with the firing-pinhalf-cocked, it is merely necessary to depress the trigger as the boltis bein breeched until the heel 43 slips past the sioulder 82 of thesear and then releasing the trigger so that the said heel will slidealongthe inclined edge of the sear whereby to prevent operation of thetrigger,

as will be evident.

The gun may be used as a single loader, when desired, by forcing asingle cartridge into position on the carrier-plate when the action isopen.
